and the like,in connection with which it is very often desirable to have the primary fuel tank carried on the vehicle at a level below the carburetor.

The object of the invention is, to provide a device of simpl". construction, economic of manufacture an highly eficient in automatic operation with particular relation to the construction of the vacuum tank portion thereof, to which the liquid fuel is elevated as by the suction of the engine, and intermittently discharged therefrom to be fed by gravity to a vaporizin device, as'for instance, to the float cham er of a commercial carburetor; 1

Other objects andadvantages relate to the detail of construction of the vacuum tank as will hereinafiter appear from the following description, taken in connection with the accompanying drawings, in which-- Figure 1 is a somewhat diagrammatic view of the liquid feeding device assembled with a low level fuel tank and a carburetor and manifold for combustion engine, the auxiliary tank being in cross section and somewhat enlarged in order to show detail.

Fig. 2 is a perspective view of top of vacuum tank showing float-and conneotwns. Fig. 3 is a detail view in cross section of valves.

4 is a detail of combination valve piston.

As shown, the invention comprises a vacuum tank 1 having suitable connections through a fuel pipe 2 with a primary fuel tank 3', a second connection, as through to suction pipe 4, with any source of suction,

engine, and a third connection as through pipe 6 with a, care bureter 7. Y

The invention herein centers about the construction of a vacuum tank 1 which comprises a sheet metal tubular body portion 8 preferably cylindrical and having its lower end closed by end wallw and divided into two chambers 10 and 11* As lndicated in Fig. 1 these two chaidhers are constituted a vessels, each opening upwardly. The outer chamber 11 is considerably longer and .'deeper than the inner chamber 10 and sufi l ciently larger in diameter to leave s ace foe an inturned flange 12 at its brim. hempper and inner chamber 10 is provided with a cover portion 13 provided -with \open it' 14: near its circumference in order that it may be bolted or fastened to the Tinturnetl flange 12.v

Underneath this cover portion 13 is IBM? tened by any means the chamber 10. The cover portion 13 is provided with .a fuel intake opening (connected by the pipe 2 with the supply tank 3 as shown innFig. 1, another opening connected by a pipe 4, with the intakemanifold 5 of an engine and a third opening fitted with a vent pipe 15 It should be understood that the pipes 4 and 15 are controlled by valverseats 16 and 17 respectively, which are so controlled by a common piston valve 18 that they can only open alternately. V See Fig. 3. When the piston valve seat 16 is open, and the piston valve seat 17 is closed, the engine suction is permitted to effect a reduction of ressure within the chamber 10 thus causing a flow of fuel throu h the pipe 2 into the vessel and causing t e float 19 to rise. The float 19 is connected, however, by a trip lever 20 and fulcrumed at point 21 to the end of a downwardly extending support lug 22. At the outer end of the, trip lever 20 at point 23 there isattached a tension spring 24; whose opposite end is connected to the outer end of a trip lever 25 which in turn is fulcrumed at a point 28 being supportedby a downwardly extend- 100 two separate cupsaor l turned lug, a cup-shaped valve seat, channels In testimony whereof I afiix my signature alt} bottom of sald cups an?l efxtending out to in the presence of two witnesses. t eir circumference, a note ormed at center of the common valve piston to engage the JOEL LEWIS 5 upturned arm, a common valve piston Witnesses:
